ABSTRACT:
An apparatus for hardening rails having a rail foot, a rail head, which is to be hardened, and a web between the rail foot and the rail head comprises a dip basin for receiving the rail head, a manipulator for receiving from a feeder individual consecutive rails supported at their head and foot and for dipping the head of each rail into the dip basin, and a delivery conveyor for carrying the treated rails away from the dip basin. In order to provide such an apparatus in which the manipulator which has a simple design and which permits a monitoring of the rails as they are handled, the manipulator comprises carrying arms, which are disposed on opposite longitudinal sides of the dip basin and are displaceable in height and pivoted on an axis which extends in the longitudinal direction of the dip basin and said carrying arms have supporting brackets, which are so arranged that when the rail is in position for being hardened with the rail head at the bottom of the rail the supporting brackets protrude from the carrying arms toward the web of the rail and engage the rail foot from below.
